You must have the battery installed in order for CPU to run at full speed on most ThinkPads.

T410 with integrated graphics should be fine with 65W adapter. The ones with nVidia require a 90W unit.
Which one do you have?
Most importantly, why would you run a machine without the battery to begin with?

Please clarify one thing:
Is it when the battery goes DOWN to 93% that the screen starts having issues OR is it when the charge goes ABOVE that percentage?
